Answer:

[tex]AD = 6[/tex], [tex]DC = 14[/tex], [tex]\angle A = 114^{\circ}[/tex], [tex]\angle B = 66^{\circ}[/tex], [tex]\angle C = 114^{\circ}[/tex]

Step-by-step explanation:

From Euclidean Geometry, parallelograms satisfy the following properties:

1) [tex]\angle A = \angle C[/tex], [tex]\angle B = \angle D[/tex]

2) [tex]\angle A +\angle D = \angle D + \angle C = \angle C +\angle B = \angle A+\angle B = 180 ^{\circ}[/tex]

3) [tex]AD = BC[/tex], [tex]AB = DC[/tex]

By 3):

[tex]AD = 6[/tex]

By 3):

[tex]DC = 14[/tex]

By 2):

[tex]\angle A = 180^{\circ}-\angle D[/tex]

[tex]\angle A = 180^{\circ}-66^{\circ}[/tex]

[tex]\angle A = 114^{\circ}[/tex]

By 1):

[tex]\angle B = 66^{\circ}[/tex]

By 1):

[tex]\angle C = 114^{\circ}[/tex]

Answer:

Two angles and the non-included side of one triangle are congruent to the corresponding parts of another triangle. Which congruence theorem can be used to prove that the triangles are congruent? Two sides and the included angle of one triangle are congruent to the corresponding parts of another triangle.

It might be 2 not 100 percent sure

Answer:

isosceles (based on sides) and right triangle (based on angles)

Step-by-step explanation:

This is an isosceles triangle because two of the sides are the same distance (it is in cm.). This is also a right triangle because at point B the two lines are perpendicular (using their slopes).

Answer:

For 100 minutes

Step-by-step explanation:

Step one:

given data

Oh phone company

monthly plans plan a cost $13 plus an additional $.14 for each minute of calls

let the number of minutes be x, and the total be y

y= 13+0.14x--------------------1

Plan B cost $18 plus an additional of $.09 for each minute of calls

let the number of minutes be x, and the total be y

y= 18+0.09x--------------------2

Step two:

Equate 1 and 2 above

13+0.14x=18+0.09x

collect like terms

18-13= 0.14x-0.09x

5=0.05x

divide both sides by 0.05

x=5/0.05

x=100 minutes

Answer:

She is less than Levi

Step-by-step explanation:

Levi has literally decades more experience of fighting titans than Mikasa. Also, as revealed in the latest chapters, both are part of the Ackerman family which was the product of titan experiments. Also, five seconds don't really help Mikasa. So, yeah, Levi wins, no doubt.

Answer:

y=-[tex]\frac{1}{2}[/tex]x+[tex]\frac{3}{2}[/tex]

Step-by-step explanation:

First, calculate the slope of the line that is perpendicular to the equation of line we are asked to find

m=(y2-y1)/(x2-x1)

  =(2-(-4))/(-2-1)

  =6/-3

  =-2

in this equation the slope is 2, and to find the first equation, use y=mx+b

use the point (1, -4) to find b

-4=(2)(1)+b

-4=2+b

b=-6

the first equation of the line is y=2x-6

to find the x intercept of that line substitute 0 for y

0=2x-6

2x=6

x=3

the slope of a line perpendicular to this would be the opposite reciprocal of the slope which would be equal to -1/2

for the second equation of the line to pass thorugh the x-intercept of the first line, it must pass through (3, 0), so substitute and solve for b

y=mx+b

0=(-1/2)(3)+b

b=3/2

thus the equation of the line that is perpendicular to the line through (1,-4) and (-2, 2) and passes through the x intercept of that line is y=-[tex]\frac{1}{2}[/tex]x+3/2

The equation of the line that is perpendicular to the line through (1,-4) and (-2,2) is [tex]y= \frac{1}{2}x+3[/tex]

The equation of the line perpendicular to the line passing through the points (x₁, y₁) and (x₂, y₂) is given as:

[tex]y-y_1=\frac{-1}{m} (x-x_1)[/tex]

The slope m is calculated using the formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{2-(-4)}{-2-1} \\\\m=\frac{6}{-3} \\\\m=-2[/tex]

For the line passing through the points (1,-4) and (-2,2), substitute m = -2, x₁ = 1, and  y₁ = -4 into the equation [tex]y-y_1=\frac{-1}{m} (x-x_1)[/tex]

[tex]y-1=\frac{-1}{-2} (x-(-4))\\\\y-1=\frac{1}{2}(x+4)\\\\y=\frac{1}{2}x+2+1\\\\y= \frac{1}{2}x+3[/tex]

I don’t really know which system of equation to use, but I did the work. I also think there is supposed to be an attached picture but it’s fine

Let x be students

Let y be adults

x + y = 222

5x + 8y = 1,626. <— let’s use the elimination/addition method to Solve this. Also, let’s eliminate y.

8 (x + y = 222)

-1 (5x + 8y = 1,626)

8x + 8y = 1,776

+ -5x - 8y = -1,626 <— add both of them

——————————————

3x = 150 <— divide 150 by 3

x = 5

Annalisa - 64 inches, 162.56 centimeters

Stefan - 67 inches, 170.18 centimeters

Keiko - 65 inches, 165.1 centimeters

Step-by-step explanation:

Answer:

x = - 8

3x - 2y = 18 is the same as 3x - (2x - 13 times 2) = 18

Then I used an algebra site for the rest.

It should be x = - 8

I'm guessing you want x and y solved.

Answer: x=10 and y=6

Explanation:

For X: Substitute the y-equation (y-2x-13) into the first equation (3x-2y=18) so your equation is 3x-2(2x-13)=18. Do the distribution property and the equation will be 3x-4x+26=18. Put like terms on the same side of the equal sign and combine like terms (subtract 26 on both sides) and the equation will be -x = -10. To make x positive, make both sides positive and you get x=10.

For Y: Substitute your x answer (10) into the first equation (3x-2y=18) and you will get 30-2y=18. Subtract 30 from both sides and you get -2y=12. Divide both sides by the common factor of -2 and you get y=6.
